FLEET sales slumped to a monthly year low in August as companies continued to adjust to new car buying patterns to take account of the introduction of the twice-a-year registration plate change. Society of Motor Manufacturers and Traders figures show fleet sales dropped to 38,560 last month - the first time they have dropped below 40,000 this year - down 7% from August 1999's 41,464 units.

Despite the decline, fleet sales still accounted for more than 54% of the August new car market which totalled 71,228 units, down 4.32% on August 1999's 74,444 tally. Business registrations - sales to the sub-25 fleet market - totalled 4,343 which was almost 35% up year-on-year. Year-to-date fleet sales are 1.9% up at 678,890 in a total new car market up just 0.78% at 1,444,261, of which business car sales are up 30.8% to 149,445.

The SMMT expects September sales to total almost 400,000 units - September last year saw 386,999 cars registered - with 2000 sales still on target to be 2.225 million units.

Of the major players Ford, Vauxhall and Citroen - up 7.5%, 3.5% and 6.1% respectively - were the only top 10 fleet manufacturers to report year-on-year sales rises. The Ford Focus was the best-selling fleet car, although Daewoo surprised the market by almost doubling fleet sales and taking eighth place in the manufacturers' best-selling league table last month, largely as a result of massively increased Matiz registrations.

The company said its sales boost was due to a combination of daily rental orders being brought forward to meet demand for car hire over the August Bank Holiday weekend, coupled with demand from the sub-25 sector and contract hire firms.

Fleet diesel car sales surprisingly increased year-on-year last month, although they remain behind 1999's eight-month sales total. Sector diesel sales totalled 7,232 in a diesel car market 10.6% up year-on-year at 11,480. Fleet diesel sales this year are 0.5% behind last year's eight-month tally at 112,547 (1999: 113,090) with total diesel sales 2.6% up year- on-year at 201,564 (1999: 196,480).In the first eight months of this year, Ford continues to lead the fleet market as Focus sales continue to rise while those of the run-out Mondeo continue to fall.

However, the manufacturer has seen its market share drop year-on-year from 21.66% for the first eight months of last year to 21.52% this year. Chief rival Vauxhall has seen its market share increase from almost 18% to 19.28% during the same period largely due to strong Astra and, more surprisingly in run-out mode, Corsa, while Vectra sales drop. Peugeot (up 7.7%) year-on-year, Toyota (up 19.8%) and BMW (up 47.3%) are the only other top 10 fleet manufacturers to report fleet sales rises this year.
